AttributeError：模块“pandas”没有属性“df”

Question

For a current project, I am planning to clean a Pandas DataFrame off its Null values. For this purpose, I want to use Pandas.DataFrame.fillna , which is apparently a solid soliton for data cleanups.

When running the below code, I am however receiving the following error AttributeError: module 'pandas' has no attribute 'df' . I tried several options to rewrite the line df = pd.df().fillna , none of which changed the outcome.

Is there any smart tweak to get this running?

import string
import json
import pandas as pd

# Loading and normalising the input file
file = open("sp500.json", "r")
data = json.load(file)
df = pd.json_normalize(data)
df = pd.df().fillna

Answer 1

When you load the file to the pandas - in your code the data variable is a DataFrame instance. However, you made a typo.

df = pd.json_normalize(data)
df = df.fillna()
